Editing Delocalized electron (section)

In the [[simple aromatic ring]] of [[benzene]], the '''delocalization''' of six [[Pi bond|π electrons]] over the C<sub>6</sub> ring is often graphically indicated by a circle.  The fact that the six C-C bonds are equidistant is one indication that the electrons are delocalized; if the structure were to have isolated double bonds alternating with discrete single bonds, the bond would likewise have alternating longer and shorter lengths. In [[valence bond theory]], delocalization in benzene is represented by [[resonance (chemistry)|resonance structures]].
